I don't know much about Perl but am aware of Tau Station, which was launched a few months ago. I recall reading somewhere that it includes a new Perl codebase with approaching a million lines of well written modern code.[0]
Raku is a different language, a very young one that has its adoption-for-serious-applications curve mostly ahead of it. Thus you get articles like the advent one from a few weeks ago that seriously documents a serious Raku application in a notably unserious way.[1] It's apparently only 7K or 13K lines of code, depending how you count, but well written Raku code is typically a fraction of the length of well written Perl code, so there is that.[2]
